7 Supernova Fruits Diamond Treasures Slot Review
A fruit machine floats in a nebula of purple and green, its reel frame wrapped in licking orange flames that pour off the bottom edge into the starfield, a pitted asteroid drifting past on the left. All that fire in 7 Supernova Fruits Diamond Treasures is spent on dressing up one of the flattest fruit paytables you’ll meet – seven of its eight paying symbols top out at 25x, and the game is honest about where its money actually lives: a single wild and an optional lottery bolted on top.
Apparat Gaming have strapped two ideas onto the old fruit format: a wild that detonates across the reels, and a collectible diamond side game with a four-reel prize draw. It runs on a 5×3 grid with 10 paylines, volatility at 5/5, stakes from 0.10 to 20 per spin, and a 96.10% RTP in its best configuration, with operators able to run it lower at 84.29%. The ceiling is an 11,000x max exposure. 100 Sevens – Diamond Treasures carries the same chest, and Mummy Bomb comes from the same studio.
Base Game & Features
This is a left-to-right game in the classic mould. Wins need matching symbols on consecutive reels starting from the leftmost one, with no gaps, across the 10 fixed paylines. Paylines are evaluated from left to right, and only the highest win per line counts.
The paytable is a familiar ladder, and it’s a steep one. Values are multiples of the total bet:
- 7 – 1x for three, 5x for four, 100x for five
- Watermelon – 1x for three, 5x for four, 25x for five
- Grapes – 1x for three, 2.5x for four, 10x for five
- Plum – 0.5x for three, 1x for four, 5x for five
- Orange – 0.5x for three, 1x for four, 5x for five
- Lemon – 0.5x for three, 1x for four, 5x for five
- Cherry – 0.5x for three, 1x for four, 5x for five
- Wild (Supernova) – substitutes for all other symbols; a full screen pays the highest combination
The gap between the 7 and everything else is enormous. Five sevens pay four times what five watermelons do, and ten times what five grapes manage. Below the melon, every fruit symbol tops out at 5x.
That shape means three-of-a-kind wins at the bottom of the table return half your stake. A win, in other words, is often a small loss. The table’s real money sits in one symbol, and everything else is there to keep the meter moving.
The Supernova Wild
The Supernova symbol is the wild, and it stands in for every other symbol on the board. When it lands, it explodes, transforming itself and all the symbols surrounding it into wilds.
That blast radius is what gives a flat ten-line paytable somewhere to go. A single detonation in the middle of the grid can turn a dead spin into a screen of matching fruit. It’s the only thing in the base game that can put the top of the table in play.
A wild on the edge of the grid reaches fewer neighbours, so placement matters as much as arrival. A centre-screen Supernova touching all four sides of its neighbourhood is the difference between a modest line and a board full of sevens.
Hit frequency sits at 12.33%, which is roughly one win in eight spins. With volatility at 5/5, those wins lean small and occasional rather than steady.
7 Supernova Fruits Diamond Treasures Bonus Features
There are no free spins here. The bonus content is a single side game, and it’s an opt-in one.
Diamond Treasures
Diamond Treasures can be activated for an additional bet on top of your stake. Once it’s on, small diamonds appear randomly on the reels and are collected into a chest at the corner of the screen. Every time diamonds are added, the prize draw can trigger at random.
The draw itself is a separate event: four reels spin, each carrying the numbers 0 to 9, and the four-digit number they form is paid out as a multiple of the bet when the draw ends. It’s a lottery wheel bolted onto a fruit machine.
How the side game works, step by step:
- Activate the side game for an additional bet, on top of the base stake
- Small diamonds land randomly on the reels during normal play
- Each diamond is collected into the chest
- Every chest addition can randomly trigger the prize draw
- The draw spins four reels of numbers 0 to 9
- The resulting four-digit number is paid as a multiple of the bet
The chest filling up in the corner gives the base game something to tick towards between wins, and the draw itself can pay far beyond anything the fruit symbols manage. Where that balance lands depends on what the extra bet costs, and the game doesn’t publish that figure.
There’s no bonus buy and no feature purchase of any kind. If you want the diamonds, you pay for them spin by spin.
Our Honest Verdict
Overall Rating: 6.1/10
Most of a session here is watching cherries return half your stake while a chest fills slowly in the corner. That chest is why anyone sits down at this cabinet: it’s the one thread running through every spin, and the four-reel draw behind it can pay sums the fruit symbols never approach.
The Supernova wild is the best thing in the game, because it’s the only mechanic that can rewrite a whole board in one landing. The worst is the spread underneath it: with everything but the 7 capped at 25x, the base paytable gives the wild almost nothing to work with most of the time.
This is one for players who like the old fruit symbols, want a lottery ticking away beside them, and can carry a 5/5-volatility bankroll without flinching. Anyone after a base game that pays its own way will find the fire here is mostly on the frame. For the rest, the nebula’s a pleasant place to grind.
